The invention relates to an internal combustion engine that comprises a first Brayton cycle comprising a mixed ionic-electronic conducting (MIEC) membrane that separates the O2 in the air such that the suctioned air current is free from N2; and a second Brayton cycle combined in a binary manner with the first Brayton cycle and nested with a cycle selected from an Otto cycle and a diesel cycle performed by means of oxy-fuel combustion. The second Brayton cycle transmits mechanical energy and thermal energy from exhaust gases to the first Brayton cycle. The first Brayton cycle provides to the second Brayton cycle compressed O2 from the MIEC membrane. By means of the present engine, the NOx emission of into the atmosphere, caused by the separation of N2 in the MIEC membrane, is prevented. 本发明涉及一种内燃机，其包括第一布雷顿循环，其具有从空气中分离O2的混合氧离子-电子导体MIEC膜，使得吸入的气流不含N2；以二元方式与第一布雷顿循环相结合的第二布雷顿循环，其嵌套在一个循环中，该循环选自奥托循环和通过氧燃烧进行的狄赛尔循环。第二布雷顿循环向第一布雷顿循环传递机械能和来自废气的热能。第一布雷顿循环向第二布雷顿循环提供来自MIEC膜的压缩O2。通过本发动机，在MIEC膜中分离N2防止了NOx排放到大气中。
